为什么这个脚本不能正确清理输出?

我正在尝试清理应该是简单的电子邮件脚本的输出,但它只输出一个空白页面。这是脚本:

    <?php
define("EMAIL", "info@silentpost.net");

if(isset($_POST['submit'])) {

  //include validation class
  include('./support/validate.class.php');

  //assign post data to variables
  $_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
  $_POST['email'] = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
  $_POST['message'] = filter_var($_POST['message'], FILTER_SANITIZE_STRING);

  $name = trim($_POST['name']);
  $email = trim($_POST['email']);
  $message = trim($_POST['message']);

  //start validating our form
  $v = new validate();
  $v->validateStr($name, "name", 3, 75);
  $v->validateEmail($email, "email");
  $v->validateStr($message, "message", 5, 1000);

  if(!$v->hasErrors()) {
        $header = "From: $email\n" . "Reply-To: $email\n";
        $subject = "email from silentpost.net website!";
        $email_to = EMAIL;

        $emailMessage = "Name: " . $name . "\n";
        $emailMessage .= "Email: " . $email . "\n\n";
        $emailMessage .= $message;

        @mail($email_to, $subject ,$emailMessage ,$header );

    } else {
    //set the number of errors message
    $message_text = $v->errorNumMessage();

    //store the errors list in a variable
    $errors = $v->displayErrors();

    //get the individual error messages
    $nameErr = $v->getError("name");
    $emailErr = $v->getError("email");
    $messageErr = $v->getError("message");
  }//end error check


}// end isset
?>

如果我省略以下代码,脚本将运行良好:

$_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$_POST['email'] = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
$_POST['message'] = filter_var($_POST['message'], FILTER_SANITIZE_STRING);

如果有必要,我会包含该类,但我不认为这是类的问题,因为正确删除filter_var行输出。

任何帮助都将不胜感激。

我会做两件事:

一个。确保你运行PHP&gt; = 5.2(filter_var函数的最小值)。

B中。将error_reporting(E_ALL);添加到脚本顶部,这样可以查看导致空白页面的错误。

脚本似乎没有任何问题。确切的问题是什么?如果您进行消毒或者没有输出任何输出,您的脚本是否不发送电子邮件?如果是后者,那么我认为你的脚本不会产生任何输出。

尝试在清理之前和之后回显您的内容,看看它们是否有所不同:

echo 'BEFORE<br>';
echo $_POST['name'] . '<br>';
echo $_POST['email'] . '<br>';
echo $_POST['message'] . '<br>';

$_POST['name'] = filter_var($_POST['name'], FILTER_SANITIZE_STRING);
$_POST['email'] = filter_var($_POST['email'], FILTER_SANITIZE_EMAIL);
$_POST['message'] = filter_var($_POST['message'], FILTER_SANITIZE_STRING);

echo 'AFTER<br>';
echo $_POST['name'] . '<br>';
echo $_POST['email'] . '<br>';
echo $_POST['message'] . '<br>';
